Re: It is possible to produce an idiot proof interface.
We had all the old crap in those machines. Apart from the 1st gen Sony CD drives ( complete with caddy ) that came in at about £400 a pop everything else was pretty long in the tooth for the early 90s - kyocera and various other 25Meg MFM drives, no-name wd1003 controller cards, various no-name MDA cards. If you were lucky you had a white screen monitor rather than the usual orange. Ahhh those were the days :-)
